honestly, the obsession with buying tools before you've even got a solid page is the fastest way to burn cash for zero return. Most people here are overthinking it.
fix the basics first. Clear titles, meta descriptions, H1s that actually match search intent - not what you think people are searching for. sanity handles this fine if you've set your schema up properly.
Google Search Console is free and most people underuse it. Connect all your sites. It shows you exactly which queries are already pulling impressions - optimise those before guessing at new keywords.
for content ideas, Ahrefs Webmaster Tools (free for your own domains) plus Google's 'People Also Ask' gives you real questions your audience is asking. no paid subscription needed at this stage.
the problem with Writesonic (or any AI content generator) isn't the tool itself - it's that people pump out generic pages with no tie to actual search intent or entity relevance. that's why traffic never compounds.
here's what actually works when you're early stage: one genuinely useful page that answers a specific question outperforms ten generic AI pages every single time. Pick one topic, write something people actually want to read, then build from there. everything else is noise.
